rdf rotary kiln

Feb 01, 1993 · Based on technical and environmental considerations, the analysis of burning refuse-derived fuel (RDF) in a cement kiln shows that no special firing technology has to be installed except that of the RDF handling system, that there is an upper limit to the total fuel consumption (no more than 30 per cent) for firing RDF and that there is no increase in the emission levels of air pollutants (including …

Aug 01, 2017 · Cement production in rotary kilns requires large amounts of thermal energy, which is provided by combustion of different fuels. Substitution of fossil fuels by refuse derived fuels (RDF) can minimize production costs and reduce CO 2 emissions, but often causes displacement of the sintering zone, impacts flame stability and cement quality

use of rdf as a kiln fuel. final report (technical report

Abstract Refuse derived fuel (RDF) has been experimented with and/or proposed for use in kilns for the production of portland cement, lime, and expanded shale (a form of lightweight aggregate). Technological issues affecting the use of RDF in kilns are reviewed as are the results of trials in which RDF has been used as a kiln fuel
